+DeepSeek's API has been experiencing significant reliability issues for the past 24-48+ hours, with many users reporting downtime and overload problems.
-However, the results can vary significantly depending on which provider is serving the model.
 
-This article compares DeepSeek V3 results from multiple providers to help you choose the best option for your needs.
+If you're affected by these issues, several alternative providers offer access to DeepSeek models. This article compares their performance on aider's polyglot benchmark to help you choose a reliable alternative.

+export OPENROUTER_API_KEY=<your-key>
+aider --model openrouter/deepseek/deepseek-v3
+```
